Polk Audio Atrium 5 Speakers (Black)

5-inch (12.7 cm) long-throw mineral-filled polypropylene cone driver with butyl rubber surround pumps out surprising bass response from a compact design
3/4-inch (19mm) anodized aluminum dome tweeter with rubber surround and neodymium magnet for better power handling and smoother response
Broad coverage baffle design, adapted and applied from our current Atrium design but with subtle improvements in the new Atrium series
Polk all-weather certified, Atrium series speakers exceed baseline industrial and military specifications for environmental endurance (ASTM D5894-UV Salt Fog, Mil Standard 810 Immersion, Mil-Std 883 Method 1009.8 for salt and corrosion) – certification means Atrium speakers can effortlessly withstand the worst Mother Nature can dish out, whether its extreme temps or heavy rains, with certification like this, your kitchen or bathroom installation is a cakewalk for Polk all-weather speakers
Durable, mineral-filled polypropylene cabinet design, with molded-in bracing, sounds like a real speaker (not “an out of doors speaker”) and survives years of seasonal changes, for actually great sound, it doesn’t matter what the weather
Patented dynamic balance and Klippel optimization technologies ensure the very best material performance, getting rid of driver and tweeter “artifacts” for more realistic sound reproduction at low and high volume levels
Aluminum grilles and bracket, with stainless steel and brass hardware – no rust, ever
Gold-plated 5-way binding posts for the most safe, dependable hookups
To be had in durable, weatherproof black or white paintable finishes
You need to fill a large open out of doors space with big, full-range sound – the new Atrium series has a more steeply-angled baffle design that maximizes critical mid- and high-frequency dispersion over a large area, without sacrificing the detail
